COKE-'OVEN'.

Specification of Letters Illatent.l .Patented D130, MD, H9145,

Application filed November 24, 1914. Serial No. 873,735.

To all whom t may concern:

Be it known that I, ERNST I-IINsELMANN, a citizen of the German Empire, residing at Essen-on-the-Ruhr, Germany, have invented certain new and useful Improvements in Coke-Ovens, of which the following .is a specification.

My invention relates to coke ovens and more especially to coke ovens heated from below.

The object of my invention is to provide a coke oven of this type which can be heated optionally with rich or poor gases, that is to say, with gases possessing high or low heating capaclty.

According to my invention, in order to allowthe oven to be heated with poor gas, regenerators are inserted between the channel brick columns serving for the admission of rich gas, the poor gas passing into the regenerators through gas ues adapted to be controlled from the passage below the burners. The preliminary heating of the air is e'ected in regenerators located sidewise of the burner battery. In order to facilitate the distribution of the combustion gases over the different poor gas regenerators a` controlling device adapted tobe operated from the passage below the burners is inserted in the main Hue behind each regenerator.

In the accompanying drawings I have shown my invention in the form which is now preferred by me.

Figure 1 is a vertical longitudinal section through a coke oven according to my invention. Fig. 2 is a cross section on line C-D of Fig. 1. Fig. 3 is a cross section on line A-B of Fig. l. Fig. 4 is a horizontal section upon the line E-F of Figs. 2 and 3. Fig. 5 shows a reversible burner on a larger scale.

Referring to the drawings a is the main gas lue adapted to be connected with either a poor or a rich gas generator. The diameter of this main lue should be great enough v to admit also the necessary amount of poor gas.

Below each heating wall a distribution pipe b is connected with the main flue, said pipe being adapted, according to the' position of the supply tubes, to feed gas to one or the other side of each heating partition.

When the oven is being heated with rich gas, the gas passes into the channel bricks d and d (Fig. 1) through supply tubes e of small diameter. Near the upper end of the columns of bricks d and d the air for com- -sume the position shown bustion, after having passed through the regenerators R or R alternately connected by means of canals K and K with the outer air and with thehchimney respectively, escapes through the apertures z" (Fig. 4) and mixes with the gas. The small regenerators r and 1" arranged between the channel brick columns-d al are cut oit in this case by means of valves s and s.

If it is desired to heat the oven with poor gas, the elbow joints carrying the supply tubes e are turned 180 degrees, so as to asin dotted llines in Figs. l and 5, the supply tubes e being replaced by larger ones e. These supply tubes are then connected with the regenerators r, 7^ by opening the valves s, s.

When the air for combustion enters through the regenerator R andthe burnt gases escape through the regenerator It', then the valves s, s and c, 0 are adjusted so as to secure for each regenerator theamount of waste heat necessary for obtaining the temperatures required for` the combustion. In order to render possible the distribution of the waste heat-over the small regenerators 1', r', small valves L (Fig. 3) are inserted in front of the collecting tlues f and f (Fig. 2). The poor gas rising through the regenerator 1^ after being heated enters the heating partition at g. The air for combustion is admiXed to it after passing through the big regenerator R and the canals i, exactly as in the case of rich gas.

I claim l. In a coke oven adapted to be heated from below, the combination of a series of long channel brick columns, a series of regenerators disposed between said columns, a series of short channel brick columns connected with said regenerators, and means for supplying gasto said long and short columns in alternation.

2. In a coke oven adapted to be heated from below, the combination of a series of long channel brick columns, a series of regenerators disposed between said columns, a series of short channel brick columns connected with said regenerators, means for supplying gas to said long and short columns in alternation, a main liuc connected with said regenerators, valves 1n sa1d main flue, and

of gas supply tubes, a series of long channel brick columns disposed above said supply tubes and adapted to befed with rich gas, small regenerators disposed between said columns and adapted to be fed with poor gas, short channel brick columns connected with said regenerators, and means for alternately connecting said gas supply tubes with said long and short channels respectively.

4. In a coke oven adapted to be heated from below, the combination of a plurality of gas supply tubes, a series of long channel brick columns disposed above lsaid supply tubes and adapted to befed with rich gas,

for alternately connecting said gas supply tubes with said long, and short channels respectively.

In testimony that I claim the foregoing as my invention, I have signed my lname in presence of two subscribing witnesses.
